2 Claims. (Cl. 219-35) This invention relates to the general art ofbeauticians appliances and, more specifically, is for an improved devicefor heating various implements that are used by hairdressers, as forinstance irons, combs, etc.

The object of my present invention is to devise a container within whichmay be placed the implements to be heated, together with means wherebythe heating may be preliminarily set for a desired temperature andautomatically discontinued when such temperature is reached.

Another object is to devise suchv an appliance with a signal light thatwill be automatically extinguished when the heating is discontinued.

Another object is to devise such an appliance with means forconveniently and etiiciently supporting the handle portions of theimplements when in heating position.

A still further object is to devisesuch an appliance with means forconveniently supporting the implements either before or after placingthe same within the container for heating.

Other objects will appear from the following description and claims whenconsidered together with the accompanying drawing.

Fig. l is a perspective view of my present device;

Fig. 2 is a wiring diagram of the electrical means;

Fig. 3 is an end elevation of the device.

Reference will now be had to the accompanying drawing in detail althoughit is to be understood that the present form of disclosure is merely forthe purpose of illustration and that there might be variousmodifications thereof without departing from the spirit of my inventionas herein set forth and claimed.

Upon the base 1, which may consist of any suitable material, there istixedly mounted the duplicate combined leg and end members 2 and 3. Eachof these members has a pair of legs 2a and 3a, respectively, aixed tothe base 1 and is open through the upper parts 2b and f 3b,respectively. The parts 2b and 3b may be of circular or polygonal formand are adapted to receive and hold the ends of the tubular` bodyportion 4 which may be of substantially the same cross section as theupper parts 2b and 3b so as to have interengagement therewith. That is,the ends of the body 4 may have abutting engagement against the portions2b and 3b, and the annular members 4a and 4b may surround the body part4, thereby providing seating engagement for the ends of the body 4.These parts are held in assembly by the oppositely disposed rods 5 thatextend through the upper parts 2b and 3b and the annular members 4a and4b and alongside the body part 4. By tightening the nuts upon thesebolts, these parts may be held in assembly, as indicated in Fig. 1 ofthe present drawing.

Also mounted upon the at top of the body part 4 and extending the fulllength thereof so as to have clamping engagement at its two ends betweenthe upper portions 2b and 3b, is the heat-conducting strip 6 upon whichis xedly mounted the thermometer 7. The strip 6 may be formed as theupper part of the wall of the body 4 so as to be exposed directly to theheat within the container and the remainder of the container wall mightbe heat-insulated. Or the entire outer wall of the body 4 may beheat-insulated except to the extent of the base of the thermometer 7 soas to expose the same to the heat within the container.

Within the wall of the container body part 4 there are concentricallyarranged a plurality of electric heating coils 8 for different degreesof heat, as for instance 100 degrees, 200 degrees, 300 degrees, 400degrees and 5 00 degrees, respectively, as indicated in the accompanyingdrawing. Each of these heating coils may extend the full length of thebody part 4 of the container and they are all continued in the form ofwiring connection through the cable 9 to the rotatable hand switch 10near the one end of the base 1; and this switch in turn has an electriccord with a plug 9a for insertion in a base socket when it is intendedto install this device. This switch has points of contact correspondingto the several different degrees of temperature as above referred to andas indicated in Fig. 2 of the present drawing; so that, upon contactingthe hand switch 10 with one of the companion contact points, there maybe then obtained a corresponding temperature within the container. Thatis to say, the circuit may be closed through the 100 degree coil, forinstance, or through any one of the other coils so as to obtain thetemperature corresponding thereto.

In each of the several branch circuits including the several coils 8there is provided a bi-metallic switch 11 which is designed toautomatically open when the heat reaches the temperature correspondingto that of the coil in the closed circuit as determined by the positionof the switch 10, so that the current will be automatically cut olf atsuch predetermined selected point.

Also, a signal electric lamp 12 is enclosed within the hollow middlepart of the rotatable switch member 10 so as to be viewable through aWindow 12a in the top thereof. This lamp is in circuit with theelectro-conductive part of the arcuate switch element 10a so as to belighted whenever the switch is placed upon one of the contact portionsof this element 10a; while the intermediate portions 10b arenon-conductive electrically. Thus the light 12 will be automaticallyextinguished when the particular bi-metallic switch is opened uponattainment of the temperature for which set. Upon moving the switch 10to position upon any one of the non-conductive portions between thecontact portions, the current may be cut o and will so continue untilthe switch 10 is moved to position upon one of the contacts; and thelight 12 will also continue off during the same length of time.

The upright rack 13 aixed upon the base 1 may serve to support thehandles of the implements while the other end portions thereof are inheating position within 4the container. Such a rack may be provided ateach end of the container so as to permit the implements to be insertedwithin either end of the container.

Also, the horizontal arms 14 may be slid into and out of the body 1 uponeither or both sides thereof so as to afford means of convenient supportfor the implements either before or after the heating of the same withinthe container.

With this device there may be avoided the overheating of the implementsand the consequent damage that might be done to the scalp and hair ofthe patient. This is made possible by the automatic control hereindescribed and also the signal light further serves to indicate to theoperator whether the current is on or off, that is whether the device isor is not heating and whether the desired point of heating has beenreached.

Furthermore, with the thermometer 7 in heat-conductive relation to theinterior of the container, there will be afforded at any and all times avisible indication to the 3 operator as to the temperature within thecontainer and this is calculated to prove quite a practical advantagewhether the electric circuit is closed through any of the heating coilsand either before or after the temperature of the interior of thecontainer has reached the point for which set, as above explained,

Other practical advantages resulting from the present invention will nodoubt readily suggest themselves to those who are familiar with the artto which it relates.
